Water-use efficiency, photosynthetic characteristics, and high through-put phenotyping methods for soybean (glycine max) genotypes contrasting in carbon isotope discrimination
… for soybean growers across the world, and in the Midwestern US is the main limitation to grain yield. A way to protect against drought stress is for plants to use water more efficiently. Carbon isotope discrimination (CID) is a measured trait that is related to water-use efficiency (WUE), and can …
